The Clark Construction Group and Mortenson JV achieved substantial completion of Chase Center, San Francisco’s new state-of-the-art sports and entertainment complex. The team handed over the keys to the $1.4-billion facility marking the end of a 30-month-long construction effort.

Chase Center’s operations team will move into the new facility to begin preparations for the venue’s first event on September 6. The centerpiece of the campus, newly-dubbed “Thrive City,” is an 18,000-seat arena that will house the NBA’s Golden State Warriors and serve as a hub for nearly 200 events annually.

The venue anchors an 11-acre site that also includes two 11-story office buildings, both components of ride-hailing firm Uber’s new corporate headquarters. The destination features an iconic glass-enclosed gatehouse, more than 20 unique retail locations and 3.2-acres of publicly-accessible plazas and open space. Two public entrances flank the arena’s east and west ends, and are sheathed in curtain wall expanses up to 75 feet tall.
